Carey's been looking slimmer than ever as of late, while performing on her Sweet Fantasy tour. Her latest stop was in Glasgow, Scotland, on Tuesday, where she rocked a bedazzled bodysuit reminiscent of Jennifer Lopez's multiple sequin get-ups for the singer's "All I Have" Las Vegas residency.

While Carey hasn't confirmed any details on her upcoming big day, we do know that Carey and Packer will be living together in an upscale gated community in Calabasas, California. The wealthy couple closed a deal to lease a mansion for $250,000 a month (or $3 million a year) in January, ET confirmed.

"The deal was done in just a few days," a source told ET. "The couple was not looking at homes for a long time. This is just the perfect place for Mariah and her family -- it's safe, it's secure, it's home."
